  1. Hi, after setting up my OpenScope initially, it connected successfully to my home wireless lan and I could access it from the tablet or browser as expected. Then, I disconnected the scope from power and tried to run in on a power bank. The blue light wouldn' stop blinking, so no connection to Wifi anymore. I re-attached to the computer assuming the power bank had not enough power, but also there the scope wouldn't re-connect to Wifi. I checked my Fritz!Box if the channel had changed to something above channel 11, but it is a safe channel 1. Any idea what may have happened here? Thanks, Jos
  2. Hello i'm using 2 ZedBoards cards with Vivado 2017.4 (for the record - i've tried to work with 2018.1 but from some reason there was a problem with the wifi's library and someone here at the forum suggest to work with 2017.4. link to this post: https://forum.digilentinc.com/topic/17224-pmod-wifi-sdk-problem/#comment-42818 the 2 ZedBoards are connected with the PmodWiFi module, this module has been tested and the hardware is working fine. my goal is to transfer a 120*160 matrix of integers from one zedboard to another. i've succeded to transfer string or several integers between the boards. the project are based on the tcp client and tcp server which exists in the examples inside PmodWiFi library. (also tried the UDP examples, didn't work). i'm sending each time an array of 160 elements. so in total in each transfer there are 640 bytes of data. the function being used is: tcpSocket.writeStream((u8*)mat,160*4)) in while loop until 120 transfers are being made. the current situation is that i'm not getting all the packets at the second card. in average 15-20 packets from total 120 packets are recieved. after a research i've made, i get an offer to put the function -> DEIPck::periodicTasks(); after every write stream but it didn't work. putting sleep(2) after each send also didn't solve the issue. attached a screenshot of the relevant code which will help to explain how the send data works. i'll be glad if someone could help with this topic or refer me to relevant project.

    Pmod wifi SDK problem

    Hi i'm using Vivado 2018.2 + Zedboard, my goal is to use the WiFiScan from the examples attached to Pmod WiFi folder. i have build the project in vivado section and exported it to SDK at that point i'm creating new application project, choose C++ project and select finish. i'm getting the following errors: flexible array member 'DHCPDG_T::options' not at end of 'struct DHCPMEM_T' DHCP.h ‪/proj_bsp/ps7_cortexa9_0/include/DEIPcK/utility‬ line 216 C/C++ Problem flexible array member 'DHCPDG_T::options' not at end of 'struct DHCPMEM_T' DHCP.h ‪/proj_bsp/ps7_cortexa9_0/libsrc/PmodWIFI_v1_0/src/DEIPcK/utility‬ line 216 C/C++ Problem flexible array member 'SMGR_T::rgPages' not at end of 'class TCPSocket' HeapMgr.h ‪/proj_bsp/ps7_cortexa9_0/include/DEIPcK/utility‬ line 145 C/C++ Problem flexible array member 'SMGR_T::rgPages' not at end of 'class TCPSocket' HeapMgr.h ‪/proj_bsp/ps7_cortexa9_0/libsrc/PmodWIFI_v1_0/src/DEIPcK/utility‬ line 145 C/C++ Problem flexible array member 'SMGR_T::rgPages' not at end of 'class UDPSocket' HeapMgr.h ‪/proj_bsp/ps7_cortexa9_0/include/DEIPcK/utility‬ line 145 C/C++ Problem flexible array member 'SMGR_T::rgPages' not at end of 'class UDPSocket' HeapMgr.h ‪/proj_bsp/ps7_cortexa9_0/libsrc/PmodWIFI_v1_0/src/DEIPcK/utility‬ line 145 C/C++ Problem flexible array member 'SMGR_T::rgPages' not at end of 'struct DNSMEM_T' HeapMgr.h ‪/proj_bsp/ps7_cortexa9_0/include/DEIPcK/utility‬ line 145 C/C++ Problem flexible array member 'SMGR_T::rgPages' not at end of 'struct DNSMEM_T' HeapMgr.h ‪/proj_bsp/ps7_cortexa9_0/libsrc/PmodWIFI_v1_0/src/DEIPcK/utility‬ line 145 C/C++ Problem thanks for the help
  4. I'm experience a similar problem. In my case I have to use the Digilent Agent to connect and manually setup wifi every time I power up the Open Scope (I get blinking blue light only); some times my network appears in the saved network list and other times it doesn't. I'm on firmware 1.296.
  5. HI, for my new PYNQ-Z1 to connect over its "USB HOST" interface: (1) will any USB Hub do, e.g., when concurrently a USB WiFi dongle and a USB-Webcam are connected to the PYNQ-Z1? (2) what is your recommendation(s) of a "compatible" stereo camera module (cf. attachment) for the PYNQ-Z1 board ? Thanks.
  6. Hey Guys, I have a problem with the OpenscopeMZ. It does connect to wifi, but i cant add it at waveformslive with networks. There is always the error-message: No Responce received. Can anybody help me? Best, Cornelius
  7. Regarding: Zybot Project I am having an issue getting the USB WIFI Adapter to successfully connect to the internet. What is working: 1) Micro SD card Prepared for Boot on Zybo 2) Successfully able to boot and login to linaro 3) Connected a 4:1 USB hub to the USB port on Zybo and all ports are working - Tested this by connecting 1 mouse on all 4 ports, (one at a time) and the mouse works on all 4 ports 4) Camera is working fine, (motion is installed, server scripts copied to init.d and permissions changed) 5) Able to view Camera feed through IP Address but that address is issued through eth0 NOT wlan0 Hardware: 1) RA Link RT5370 USB Wi-Fi Adapter - linked for image - This adapter works flawlessly when I connect it to my PC. 2) Zybo, powered via 5V DC wall-wart power supply 3) Logitech C120 Webcam Note: Instead of connecting the zybo via HDMI, I have connected it to my router via Ethernet and am using SSH to send instructions In order to illustrate the problem: (lets look at the responses from terminal....) 1) When I type 'lsusb' (utility for displaying information about USB buses in the system) --> I get screenshot 1 - As you can see here, the WIFI adapter is detected fine 2) When I type 'ifconfig' --> I get screenshot 2 3) When I type 'lsmod' --> I get screenshot 3 - No kernel modules are installed 4) when I type 'sudo nano /etc/network/interfaces' --> I get screenshot 4 - which is detailing how I want the network interfaces to be set up 5) when I type 'sudo nano /etc/wpa_supplicant/wpa_supplicant.conf' --> I get screenshot 5 - Which is detailing the credentials of my network (you can see my password, it doesn't bother me) ISSUE: I am able to stream from the camera successfully through the wired internet connection (screenshot 2 shows that I have a valid IP address) The problem is getting the USB Wi-Fi Adapter to show up in 'ifconfig' so that I can use it for streaming. Doing so will allow me to detach the Zybo from the router's Ethernet connection and use it cord free on a battery pack. Please tell me how to set up RT5370 USB Wi-Fi properly on Linaro (for Zybo) and also connect to any network of choice

    Pmod wifi

    Hi, I have two problems regarding wifi 1- I am trying to connect the pmod wifi to an arduino uno. I looked for a library, the best I could found is the WiShield https://github.com/airsoftsoldrecn9/WiShield . Clearly, this library is for the WiShield https://www.elechouse.com/elechouse/index.php?main_page=product_info&cPath=90_186&products_id=2165 but I thought because they use the same wifi chip as the pmod wifi this could work. However, after I manage to compile the library (I attached the working library after some minor modification in order to for it to compile) and after I connected the pmod wifi to the SPI of the arduino uno nothing seems to work. I tried to debug and I noticed that the code stuck in initialization stage, specifically in the file g2100.cpp line 144 (do-while loop). Could any one be kind enough to help or, if there is a working library for pmod wifi, that would be great. 2- I have the chipkit wi-fire rev C,I tried the example WifiTcpEchoServer which is working just fine. However, I need to make the kit act as TcpClient, so I tried the example WifiTCPEchoClient, however it does not work. The problem is that the kit does connect to the router, however, it does not connect to another tcp server on the PC. I tested to see if that is a problem with firewall, but it is not. I tired to debug and I noticed that the code stops at deIPcK.tcpConnect function. I appreciate any help. Thanks WiShield3.zip
  9. Received my OpenScope MZ a couple of weeks ago and am now just trying to configure it. My application is doing field measurements where this is no WiFi network available. There is only the Android device and the OpenScope MZ. Could some kind soul give me a step-by-step procedure how to accomplish this, starting from opening the shipping box for the first time and ending up with the OpenScope talking to Waveforms Live on the Android device? Many thanks! dwayne
  10. Hello! I'm new to chipKit development but need to build a project on this platform and hope somebody can suggest some tools and libraries to help me. I have a WF32 board that I am connecting to my Macintosh. On this board, I need to create a user interface that displays data to the user on a tablet and communicates this data to the tablet over the on board wifi interface. I would like to use this wifi interface to communicate a data file to a base station and eventually over a cellular connection back to a server over the internet. I have scanned the projects on the digilentinc site and found nothing in the way of user interfaces, tablets or wifi the way that I want to use them. I found the displayCore library on the chipKit site which seems like it might be a solution: http://chipkit.net/p-p-pic-up-a-tft-with-chipkit-and-displaycore/ But I have been unable to get any response back from requests to join this forum. Can somebody please tell me if there is a tool set or project out there that does what I want to do? Thanks! squirrel1
  11. I'd like to use my OpenScope MZ on the go, so I was hoping I could have it connect to the hotspot I can create with my Android phone. It seems to be connected (solid blue led, blinking yellow led), it's also connected to my computer through usb where I can see it's ip address, but when I try to add the device on the WaveForms Live Android app or on waveformslive.com I get the "No response received" error. Even a ping to the ip fails. I also confirmed the ip using the Hotspot Manager app on Android. I tried running through the WiFi setup again. I have up to date firmware (1.296.0). When I try the same on my regular home wifi network I can add and access the device. Could I be doing something wrong here? Have you guys connected the OpenScope MZ to a Android hotspot?
  12. As already mentioned in your FAQ, there are some issues with noise/peaks on the oscilloscope channels of the OpenScope. In the example (OpenScope_Peaks.png) you can see distortions of up to 200mVpp. The test setup: Ch1: connected to DC1 @ 157mV Ch2: shorted to GND OpenScope is powered by a 5V USB power bank I noticed, that the distortions can be completely eliminated by touching the PCB antenna of the MRF24. It seems to work equally well if you tape down one of the insulated ground wires onto the PCB antenna. or keep protective earth close to the outer edge of the PCB antenna (e.g. between two layers of insulating tape).
  13. I finally got around to using my OpenScope for the first time. I've installed the Diligent agent and have gone through updating the firmware and calibrating. I am able to take measurements and everything appears fine. So, I decided to try the Wi-Fi. I configured it for my network and when I power it with a USB wall charger, it appears to connect and gets an IP address on my network. LED #4 (blue) is lit solid. LED #3 (green) is blinking about once a second, and LED #2 (orange) is blinking about once every 5 seconds. When I open a browser and go to that IP address (192.168.0.15), the browser is redirected to http://waveformslive.com/. When I attempt to add it as a network device, I get "No Response Received". This happens whether I use the IP address or the hostname. I'm using a Windows 10 PC and the Edge browser. What am I doing wrong?
  14. Hi! I've been playing with the low cost ESP8266 modules, that present a IP-over-WiFi as a serial device, and you use modem-like AT commands to control it. I've just put up a project that allows the FPGA to connect to my Wifi network, then send status message to a service that is listening on my Linux VM. It is all done using VHDL state machines (no software CPU), and could most probably be made a little more compact. Because the serial port is running at 9600 and the AT command based protocol overhead it is a pretty low bandwidth solution, but enough if you wanted to add some basic WiFi telemetry to a design. The ESP8266 module used was under $7 - http://www.seeedstudio.com/depot/WiFi-Serial-Transceiver-Module-w-ESP8266-p-1994.html You can find all the source on my Wiki at http://hamsterworks.co.nz/mediawiki/index.php/FPGA_ESP8266
  15. Dear Digilent, First of all, I am running Windows 10 Pro 64Bit, Vivado 2015.4 Webpack and my hardware is the Zybo Board Rev.B.3 I am trying to instantiate the PMOD WiFi Module on one of my PMOD ports (There are 6 on this board so I chose the standard PMOD JE) but I face an error when trying to add the 'vivado-library-master' folder which I downloaded from GitHub. I followed this link in order to do that and downloaded the library zip from this link (via GitHub) Once I had the ~123Mb Zip File downloaded: 1) I extracted the zip to a folder near my projects 2) Opened up Vivado, created a new project, selected my board (already copied my board files earlier) 3) Opened up project settings > IP tab > Repository Settings >>> and tried to select the downloaded folder (folder NAME: vivado-library-master), screenshot included When I do this, click apply and close the project settings window, I am served a new window titled "critical messages" and it's screenshot is included in this post aswell Basically It tells me that two of the IP's in this folder namely PmodSD_v1_0 and PmodWIFI_v1_0 could not be included because Vivado is "unable to read IP file" **What I have already tried** 1) I have made sure that there are no spaces or special characters in the path to the folder containing the library 2) Downloaded this library zip file from GitHub multiple times to ensure that my downloaded isn't corrupt 3) Restarted my computer, created a fresh project and tried this again, this time choosing by board as the Arty FPGA Dev Board as done in a youtube video called "Pmod Monthly - November 2016 - Adding WiFi to your Digilent FPGA or Zynq Board" The problem still persists and I am stuck! Please help!

    Wireless Pmod For Zybo And Zedboard

    We recently bought a PmodWifi for use with our Zybo board and discovered there is no Linux driver for it. The download for the module does include a driver for use on the ChipKit microcontroller, which could be ported to Linux. However, we'd rather spend our development time on other tasks. We're going to try an SD card with an Atheros AR6233 WiFi/Bluetooth module on it. This module contains an AR6003 chip, whose driver is in the Linux kernel. Since we're booting from SD, we'll use the PmodSD to attach the WiFi. Assuming the card and driver works, it would be cool to have a periphal module containing the AR6233 to simplify assembly, purchasing, etc.
  17. I am wanting to use a ChipKit board for a robot using WiFi and CAN. I am only seeing boards with wired network and CAN, is there an option I am not seeing? The MAX32 has the can, but it has an Ethernet also - can the MAX32 be used with the WiFi Shield? The WiFire or WF32 have the WiFi, but not the CAN, the only shield I see here that has CAN is the Ethernet Shield, will they work together? or am I better off with a Wi-Fire or WF32 and a CAN shield from else where like https://www.sparkfun.com/products/10039 Thanks Bill
